CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 551,835, dated June 9,1896.

Application filed April 27, 1895. Serial No- 54'7,303. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES H. TAYLOR, a citizen of the United States,and a resident of South Orange, Essex county, and State of New Jersey,have invented new and useful Improvements in Oar-Couplers, of which thefollowing description, taken in connection with. the drawings herewithaccompanying, is a specification.

My invent-ion relates particularly to that class of car-couplersemploying a verticallyoperating pin or bolt as the means for looking thecoupling hook or knuckle in a closed position, and has for its object toprovide a cheap and simple device or means for limiting the upwardmovement of the said locking-pin when being raised to release thecoupling-hook, to prevent its being withdrawn from the opening in thedraw-l1cad in which it operates. This object I secure by means of theconstruction and arrangement of parts hereinafter set forth in detail,and pointed nt in the claims.

Referring to the drawings, Figure 1 represents a side view of a couplerembodying my invention, and Fig. 2 a vertical section through thedraw-head at a line through the locking-pin.

To explain in detail, a represents the drawhead of the coupler, a thepivoted horizontally-moving coupling hook or knuckle, and b thevertically-operating locking-pin, which is supported within an opening ain the drawhead and adapted to engage with the inner arm a of thecoupling-hook to lock the latter in a closed position in a manner wellunderstood by those skilled in the art.

In the present instance, and according to my invention, I have providedthe pin b with a longitudinal groove 1) in its side, which terminates ata point above the lower end of the same, whereby a wall or projection 11is formed, with which latter a pawl c is adapted to engage, as will bedescribed. The said pawl o is pivotally supported at c in a suitableopening in the draw-head, with one end 0 projecting in a normal positioninto the pin-opening a? in the draw-head and within the groove 12 in thelooking-pin, as clearly shown in Fig. 2. hen the end of the pawl is insuch normal position, it is adapted to engage with the wall orprojection 19 on the locking-pin,when the latter is raised to releasethe coupling-hook, and prevent its being pulled or withdrawn from itsopening in the draw-head.

The upper edge or surface of the pawl c at a point between itspin-engaging end 0 and its pivot-support is provided with a part thereofextending at an angle to the line of draft of the locking-pin whenengaging therewith, forming a bearing-surface 0 which latter is heldagainst a corresponding surface ain the draw-head and is adapted toengage and have its bearing thereon when the locking-pin is drawnagainst the end of the pawl, in such manner that the strain upon thepivotpin or support will be relieved, as will be readily understood.

The pawl is movably held in its normal operative position for limitingthe movement of the pin as described, in the present instance shown, byreason of its rear end 0 being weighted or made heavier than itsopposite pin-engaging end. It is obvious, however, that a spring orother equivalent means might be employed in lieu of the weight asdescribed and accomplish the same result. In order to remove the pinfrom its position in the draw-head, it is necessary to move the end 0of. the pawl away from the path of the projection b on the locking-pin,which is accomplished by raising the rear end 0 of the pawl and therebythrowing the opposite end into its recess in the draw-head and outsideof the pin-opening of. "When the end of the pawl is thus located, itwill be obvious that the pin may be readily removed without obstruction.

Having thus set forth my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. The combination in a car-coupler, with the coupling device, and avertically-moving locking pin or bolt provided with a projectionthereon, of a pawl pivotally supported in the draw-head of the coupler,with one end movably held in a normal stationary po said pin and theprojection thereon, substantially as described and for the purpose setforth.

2. The combination in a car-coupler with the coupling device, of avertically-moving locking -pin provided with a longitudinal groovetherein terminating at a projection near the lower end of the pin, apawl supported in the draw-head with one end movably held in a normalstationary position 62(- tending into said groove in the locking-pin,and means for holding the pawl in such position, substantially asdescribed and for the purpose set forth.

3. The combination in a car-coupler, with
